When the body produces high levels of TSH, it normally indicates a problem within the thyroid gland. Low levels of TSH indicate an overactive thyroid gland. TSH tests may be affected in one way or another if the patient is pregnant, has liver disease, suffers from a systematic illness or uses certain drugs, notes Lab Tests Online.

After diagnosis, doctors will recommend the use of synthetic thyroid hormone called levothyroxine. This oral medication is aimed at reversing the signs and symptoms of hypothyroidism. Individuals may start observing improvement within 2 weeks of taking the medication.
